Simulation of room temperature sustained load cracking of commercial purity titanium

Experimental results and finite element (FE) simulations of the deformation and fracture of commercial purity titanium (CP Ti) at constant load and room temperature are presented. Results are shown for two batches of CP Ti having different equivalent oxygen (O-eq) contents 14 and 19%. The FE analysis used a unified visco-plastic material model. The simulations are compared with experimental results. tit a given load CP Ti with a 14% equivalent oxygen content gives a shorter failure time than for 19% O-eq CP Ti. This is confirmed by the FE simulations.
